WebMar 5, 2024 · There are three types of open-circuit faults: an upper bridge arm IGBT fault (type I fault), a lower bridge arm IGBT fault (type II fault), and two IGBT faults that occur at the same time (type III fault). It is only in mode 2 and mode 3 that the operating state is affected by an IGBT open-circuit fault and that it changes the current flow. WebWhile the FZ800R33KF2 can turn-off very fast, less than 200nS, its turn-on time is much slower. Therefore, a gate boosting circuit is needed to maximize the IGBT switching speed at turn-on. The booster delivers 22A into the gate with a peak voltage of 20V. As the gate current begins to rise, voltages develop
